What are peoples views on buttons that are also menus. The Irish Times site below has used a drop down icon next to each nav item showing a menu, This allows users to see into a section before navigating to it. I found this very off putting when it was first launched, as accidently hovering over these, cause the story you were viewing to be hidden momentarily.
From a user point of view I had to 'get used to' this which is never a good idea.
Does anybody have other examples of this done better or worse. Its a real issue for high volume content sites, such as newspapers, who need to show a lot, in limited space.
